Join Paul F. Aubin for an in-depth discussion in this video Splitting section lines, part of Revit: Tips, Tricks, and Troubleshooting.
- [Instructor] Sometimes you want a section line or an elevation line to cut through more than one portion of the model simultaneously. Very easy to accomplish. So, let me start by laying out what I want to do here. I've got this balcony condition over here, and if I look at this Overall section, it shows it quite nicely. But what I might want to do is actually also simultaneously section through this little ante space as well. So I could create a completely separate section for that, but sometimes it's nice to actually show them side-by-side for comparison, so you can kind of, you know, infer relationships.
So I'll make a whole new section for this purpose. So I'll come up here to my Quick Access toolbar, click the Section tool, I'm going to click right below this window and drag up past the outside of the building like so. Then, I'm going to fine-tune that section just a bit by cropping it in closer to the building in all three directions. Click my Modify tool to cancel, and then let's double-click, open it up, and see what we've got. So, it's showing essentially the same thing as the previous section. So now let's go ahead and modify that.
Now to do that, we have to go back to the Plan view, so I'll close that section, select the section line, and then on the context ribbon that appears, you'll have a Split Segment tool. So all you need to do is click that tool, and you get this little X-Acto knife, click where you want the split to occur. So I want to actually look at this piece of cabinetry here, so I want to click below the location of that cabinetry, right about here, and then if I move left or right, it will start to split away a segment.
If my mouse is up when I go left or right, it moves the upper portion. If my mouse moves down, it moves the lower portion. So you have complete control over which portion you are splitting away. So I'm going to split the upper portion and drag to the right, and then click when I'm through that doorway. Now, you can actually split the same section more than once. So if I click again on the section line and drag out another portion, you can add as many of these little splits as you need to.
Click the Modify tool when you're finished, and that completes the command. And then if you come back and select the section line, you'll now have a series of control handles here which allow you to adjust where those breaks occur, both laterally and horizontally. We can adjust them pretty easily just by dragging the grips. If you want to remove one of the breaks, simply drag this back to the original position, and you'll kind of feel it snap, and when you let go, it will remove that particular elbow.
So very easy to add the splits and then to come back and remove the splits later. Now, if I open this section, so I'll deselect, double-click the blue section head, you can now see that the right-hand side is cutting a different portion of the building than the left-hand side. So now what I'm going to do, is using the crop region here, is I'm going to make some adjustments to this to kind of fine-tune what we're actually seeing there. I want to make this a little bit more focused on the interior, so I'll drag this control handle at the bottom and crop out the foundation.
I'll do the same thing up here at the top and crop out the roof. And then on the sides, get in nice and close to the building itself. Now, if you don't want to see that hard edge where the split occurs, then what you can do as well is select the crop region again and you'll have the small little View Break controls. You can add a View Break horizontally or vertically.
In this case, I'm going to add it vertically, and I'll click, and it will take out this big chunk in the middle. But now you've got controls on both sides and you can adjust how much of it you're seeing. So I'm going to zoom in a touch here, and drag this until I see where that line was for the split, and then drag this grip just to the left of that line. Okay, so I'm stopping the crop just on the inside of that split. And I'll do the same thing on this side.
Now, be careful that you don't drag until it touches the other one, because if you do, it'll actually remove the View break, okay, and you'll get a warning down here. So let me undo that, then try again. Drag it to right about there, maybe, a little further. Okay, what I want to see is when that line appears. There's the line, right there, so I'm now right at the split, and then I'll just drag it to the right a little bit to remove that portion of the split.
So now, at this point, if you hide the crop region, you now have a nice, clean gap there with no extra line work. But if you want to finesse it a little bit further, you could go to Annotate, use the Detail Component tool, load a family, go to Detail Items, General, Break Line, zoom in here, I'll tap the space bar once. This creates a Break Line component. If I click and place it, you can see that it includes a masking region.
So I'll take this and pull it to the other side over here. I'm going to turn the crop region back on again, so I can see where I need to move this, and I'm going to move this thing so that it's just inside the edge of that crop region there. If you go too far, it'll start to crop the Break Line. So I want to make sure I'm seeing the entire Break Line. And then, I'll drag this grip to the gap in the middle, and these grips to make it tall enough.
Drag that there. Then I'll copy the entire thing over to the other side, space bar twice to rotate it twice, and move it so that it is positioned correctly on this side, and then finally zoom in, locate the break here, and use my arrow keys to nudge it over until it's just inside the crop region. I'll deselect it, zoom out, and hide the crop region again, and that completes the effect.
So I now have these two little break marks here, which kind of make it look like this is a little two-part section. Now, of course parts are optional, but I think it adds a nice effect. Now let me go back to the floor plan here, and let's revisit this section. And we've got a longitudinal section here, and you can see that it's currently cutting through the roof. So if I open up that section, it looks a little odd here. So we're cutting through the roof, and we've got all these solar panels just kind of floating out in space there. So if I go back to the transverse section right here, where I can actually see what's going on there, this split segment feature works both in plan and in elevation, so you can split the segment in either direction.
Now unfortunately, you can't split it in both directions at the same time, so once you've split a section one way, that will become disabled in the other direction. But it's available here. I can split it right about here at the top level, and again you can either drag the lower portion or the upper portion, so I'll drag the upper portion until it's just about where the ridge is, and then click. Cancel the command, reopen that section, and that looks a lot nicer. So you can use this tool vertically as well, to, you know, just make it look a little bit nicer when it's cutting through sloping portions of the building, like sloped roofs.
And it's not limited to just sections. You can actually use this feature on elevations as well. So one more time, I'll go back to the floor plan here, middle floor plan, and I've got these interior elevations in the center here, and I'm going to consider Elevation 1-d, which is pointing off to the left, this little triangle right here. Now, you'll see that it's actually cutting through the stair right now, and if I double-click the triangle, the stair kind of looks like it's floating there. So let me close this elevation, and select that triangle.
That makes this cut line visible, and the Split Segment button becomes available. So I click it, and I'll split right next to the stair, and again, I want to pull down, so I'm dragging the lower portion, and then I'll just kind of come over here until I'm in front of the stair, and click. And so now my cut line for that elevation has that little jog in it, deselect, double-click the triangle, and now it looks a lot nicer because I'm seeing the entire stair in this interior elevation.
So the Split Segment tool is a great way to kind of fine-tune your elevation and section lines and get them to cut through just the exact portion of the model that you want them to, to make sure that each elevation and section is conveying exactly the intent that you need.

Q: Why can't I earn a Certificate of Completion for this course?
A: We publish a new tutorial or tutorials for this course on a regular basis. We are unable to offer a Certificate of Completion because it is an ever-evolving course that is not designed to be completed. Check back often for new movies.
